<apparently they are all clueless.>
Pretty much. More importantly, they were stuck in a clueless system which rammed W-CDMA down their throats, along with GSM. Sometimes governments make good decisions, such as Korea's decision to use CDMA, which has resulted in Korean companies making vast fortunes. Usually they do really dopey things.
Check out D'oh!CoMo's W-CDMA woes. You obviously missed all that.
Backhaul is easy. It's the last mile that's hard. CDMA has an advantage [as I already explained but you were obviously not paying attention = <CDMA networks don't have any special problem in that regard and on the contrary, they can fit so much data through, that the economics of upgrading backhaul are improved greatly.>] in backhaul in that CDMA has great customer utility, meaning greater value, meaning better backhaul is more economic in CDMA systems than in analogue systems supporting a few users at high cost.
People buy an end to end system when they sign up for a service. They don't care where the delay occurs - they just blame, rightly, their service provider. With heavily loaded CDMA systems, with people clicking on cyberspace, there will be big demand for backhaul and the economics of that demand translates into fatter and faster backhaul pipes. There are many ways to achieve that.
To really labour the point, it's the value delivered to subscribers which matters. CDMA can deliver that value. GPRS, EDGE, GSM, TDMA and analogue services can't. Flarion can and so can WiFi and WiMax and the like which are spectrally efficient.
W-CDMA is not all bad, but it wasn't the best solution as is now evident from the problems they have had making it work in a half-baked fashion. 1xEV-DO is fair zipping along by comparison.
